CNC Turning Centers

Features:
1. AK...M series lathe is a kind of semi-closed loop CNC turning centers, develope a new high-production machine tool base on full function CNC lathe AK series.
2. Due to equipping C-axis(spindle indexing function) and imported power tool turret, so the CNC turning centers has turning function, else increase milling and drilling functions. Realizing Z,X,C axis linkage, higher speed and higher effective, wider machining range.
3. Machining accuracy of CNC turning centers up to be IT5~IT6, roughness: Ra0.4um for non-ferrous metal cutting and Ra0.8um for ferrous metal;

1. AK...M series lathe is a kind of semi-closed loop CNC turning centers, develope a new high-production machine tool base on full function CNC lathe AK series.

2. Due to equipping C-axis(spindle indexing function) and imported power tool turret, so the CNC turning centers has turning function, else increase milling and drilling functions. Realizing Z,X,C axis linkage, higher speed and higher effective, wider machining range.

3. Machining accuracy of CNC turning centers up to be IT5~IT6, roughness:  Ra0.4um for non-ferrous metal cutting and Ra0.8um for ferrous metal;

4. CNC turning centers adopt excellent quality casting iron, casting one piece slant bed(45°), all rails are hardened and precise ground, and all axes feature reliable high torque servo motor(FANUC).

5. Heavy slant bed design and rigid heastock were FEM analyzed and optimized in the design phase.

6. Direct drive and torsion-free, large pre-loaded ball screws with dual pre-loaded spindle nuts ensure long-term accuracy.

7. Linear guides on X/Y axis for high rapid feed speeds and high positioning accuracy(AK-15M); Medium-frequency hardened guides on X/Y axis for enough rigidity(AK-25/35/45M).

8. CNC turning centers adopt Numerical control, choose excellent stability and famous brand FANUC CNC system.

9. CNC turning centers with automatic central lubrication, coolant system extend intervals between maintenance and reduce down-times.

10. Rich standard configurations meet all kinds of simple and complicated machining parts, according to customer's need, increase special configurations and different machining length.


Structure Optimization of CNC turning centers


» Machine bed: 45 °One-piece slant bed, by precision graphics analysis of bed structure and high-quality casting iron, the bed supplies high rigidity and excellent stability.
